2914* Process Control Setting
C-alpha
Adjusts the charge roller voltage used when paper with a small width is fed
from the by-pass tray. The paper width below which the correction starts
001
depends on the value of SP2-309-1.
Use this SP when an image problem (such as white spots at the center of
black dots or breaks in thin black lines) occurs when paper with a small
width is fed from the by-pass feed tray.
C-beta
Adjusts the charge roller voltage used when paper with a small width is fed
from the by-pass tray. The paper width below which the correction starts
002
depends on the value of SP2-309-2.
Use this SP when an image problem (see 2-914-1) occurs when paper with
a small width is fed from the by-pass feed tray.
B-gamma
Adjusts the development bias used when paper with a small width is fed
from the by-pass tray. The paper width below which the correction starts
003
depends on the value of SP2-309-1.
Use this SP when an image problem (see 2-914-1) occurs when paper with
a small width is fed from the by-pass feed tray.
B-delta
Adjusts the development bias used when paper with a small width is fed
from the by-pass tray. The paper width below which the correction starts
004
depends on the value of SP2-309-2.
Use this SP when an image problem (see 2-914-1) occurs when paper with
a small width is fed from the by-pass feed tray.
